Topic: powering the HS-322 HD servo (Read 4869 times)

Hey folks , i finally got this servos.they have 3 terminals (power,control,vcc)do i just connect the power terminal directly to the voltage? without any resistor???anyone has worked with this servo before? how much current does it take?how much current does the control terminal take?

Yes, obviously if I have less than 6V batteries Ill power them directly.

My setup on my line following bot ( the newest one with obstacle avoidance and green victim/tape detection ) has 6 AA batteries connected to two 5V 1.5A regulators. One regulator is to the three servos and the other regulator is for the MCU , sensors , and LCD.

But hey, why would I not want to regulate servo voltage? ( lets say i had batteries that add up to be less than 6V)What affect would that have on the servo?

Speaking of heat, your voltage regulator probably has thermal shutdown, meaning that if it overheats it will throttle down current to your servos - meaning your servos will have lower torque and lower speed.

If you really really need to regulate for servos, get a switching regulator (like 83% efficiency on average).

Consider the servo control lead to be equivalent to a microcontroller I/O connection. The current draw will probably be measured in microamps.

And I've got to agree with Admin here. You want to be passing microamps or milliamps through your linear regulator, not amps (i.e. you don't want to be using a linear regulator to regulate motor/servo voltage).

well as i saied before there is somthin wrong with the datasheet opening over my pc....dunno why,,maybe its not my pc only.thanks admin for lettin me know its 180 degrees ,,huff,, .

the most important q is how much current does the control terminal draws?why??? because i want to use the same microcontroller pin to control 3 servos or maybe 4 ,,can I do this? the micro im using provides 20mA on its pic, would that be enough for 3 or 4 servo controlterminals?
